Abstract
Convex positioning algorithm in wireless sensor networks is a commenly used range-free algorithm.In order to solve the low positioning precision problem caused by large overlap area of beacon nodes.This paper puts forward an improved algorithm based on RSSI and Convex combination.The algorithm uses the relative relation between RSSI value and distance.It further narrows the positioning region for unknown node and enhances the positioning accuracy as a result.Since the algorithm only adds one communication between unknown nodes and beacon nodes.It basically keeps the advantages of low computation and real-time of Convex algorithm.The simulation data and the experiments based on CC2430 shows that the improved algorithm has a obvious promotion on positioning accuracy and it could promote 20％-25％ in average.关键词
